  • Decline of Six Native Mason Bee Species Following the Arrival of an Exotic Congener Kathryn A
    www.nature.com/scientificreports OPEN Decline of six native mason bee species following the arrival of an exotic congener Kathryn A. LeCroy1*, Grace Savoy‑Burke2, David E. Carr1, Deborah A. Delaney2 & T’ai H. Roulston1 A potential driver of pollinator declines that has been hypothesized but seldom documented is the introduction of exotic pollinator species. International trade often involves movement of many insect pollinators, especially bees, beyond their natural range. For agricultural purposes or by inadvertent cargo shipment, bee species successfully establishing in new ranges could compete with native bees for food and nesting resources. In the Mid‑Atlantic United States, two Asian species of mason bee (Osmia taurus and O. cornifrons) have become recently established. Using pan‑trap records from the Mid‑Atlantic US, we examined catch abundance of two exotic and six native Osmia species over the span of ffteen years (2003–2017) to estimate abundance changes. All native species showed substantial annual declines, resulting in cumulative catch losses ranging 76–91% since 2003. Exotic species fared much better, with O. cornifrons stable and O. taurus increasing by 800% since 2003. We characterize the areas of niche overlap that may lead to competition between native and exotic species of Osmia, and we discuss how disease spillover and enemy release in this system may result in the patterns we document. International trade creates opportunities for plant and animal species to be intentionally or inadvertently intro- duced into novel ecosystems where they may interact with native species. One outcome of species introductions is the potential for competitive interactions with native species, especially those that are most closely related to the introduced species.

Final revision received: December 13, 2019. Accepted: December 20, 2019 Abstract Most of the studies on learning in bees have focused on the foraging context; we know little about the preferences and cognitive processes in nest-site selection, especially in solitary bees. The majority of the bee species are solitary and in contrast to eusocial bees, solitary bees’ cognition and social information use have remained largely unstudied. Solitary cavity-nesting mason bees (Osmia spp.) are an ideal system to study interspecific information use in nest choice in the wild as many species share similar nesting requirements. Here, we show that the blue mason bee (O. caerulescens)andthe orange-vented mason bee (O. leaiana) examine hallmarks of parasitization of the nests of red mason bees (O. bicornis) before deciding where to establish their own nests. They were also presented with contextual cues (geometric symbols) that could be linked to parasitization by observational learning.

  • Pollination in New Zealand
    2.11 POLLINATION IN NEW ZEALAND POLLINATION IN NEW ZEALAND Linda E. Newstrom-Lloyd Landcare Research, PO Box 69040, Lincoln 7640, New Zealand ABSTRACT: Pollination by animals is a crucial ecosystem service. It underpins New Zealand’s agriculture-dependent economy yet has hitherto received little attention from a commercial perspective except where pollination clearly limits crop yield. In part this has been because background pollination by feral honey bees (Apis mellifera) and other unmanaged non-Apis pollinators has been adequate. However, as pollinators decline throughout the world, the consequences for food production and national economies have led to increasing research on how to prevent further declines and restore pollination services. In New Zealand, managed honey bees are the most important pollinators of most commercial crops including pasture legumes, but introduced bumble bees can be more important in some crops and are increasingly being used as managed colonies. In addition, New Zealand has several other introduced bees and a range of solitary native bees, some of which offer prospects for development as managed colonies. Diverse other insects and some vertebrates also contribute to background pollination in both natural and agricultural ecosystems. However, New Zealand’s depend- ence on managed honey bees makes it vulnerable to four major threats facing these bees: diseases, pesticides, a limited genetic base for breeding varroa-resistant bees, and declining fl oral resources. To address the fourth threat, a preliminary list of bee forage plants has been developed and published online. This lists species suitable for planting to provide abundant nectar and high-quality pollen during critical seasons.

  • Pheromone Trap Colour Determines Catch of Non-Target Insects

WEARING5 1HortResearch, Mt Albert Research Centre, PB 92169, Auckland 2HortResearch, Canterbury Research Centre, P.O. Box 51, Lincoln 3HortResearch, Hawke’s Bay Research Centre, Private Bag, Havelock North 4HortResearch, Nelson Research Centre, Private Bag, Riwaka 5HortResearch, Clyde Research Centre, RD 1, Alexandra 6Author for correspondence ABSTRACT Pheromone traps were operated in five regions to determine the impact of trap colour on catch of target and non-target insects. Red or green coloured pheromone sticky traps caught fewer native and introduced bees compared to the standard white traps, and yellow or blue traps. Honey bees (Apis mellifera) were caught mainly in white followed by blue traps, while bumble bees (Bombus spp.) were most attracted to blue traps, with most of the remainder caught in white traps. Native bee (Lasioglossum and Hylaeus spp.) catches were greatest in white traps, followed by yellow traps, with a few in green traps. There was no significant difference in catch of the target species, Cydia pomonella or Epiphyas postvittana, with trap colour. Replacement of the white traps with green or red traps is recommended to reduce non- target impacts on bees. Keywords: pheromone trapping, non-target, bees, codling moth, lightbrown apple moth. INTRODUCTION The New Zealand apple industry is reliant on export markets, which place phytosanitary restrictions on insects and their damage (Batchelor et al. 1997). Leafrollers and codling moth are key pests of apples and are the target of most insecticides in the crop.
